RECORDING ATTACHMENT.

. Application med October 27, 1915. Serial no. 58,176.

with machines which playdisk records and which do not already have means for making a record in the first instance. Broadly,

the presentinyention consists of an improved attachment to be applied to such disk machines, so that records can be made thereon, although the spirit of the invention could be embodied in an attachment applicable to a cylinder machine if desired; and the attachment of course can be used for reproducing also. 1 The preferred embodiment of the invention comprises the combination of three parts, first, a bracket (detachably) secured I mechanism. If desired the block or bush-' ing might be dispensed with and the feedmechanism rotated directly from the record i'ng-tablet or the turn-table. Preferably the invention further includes a provision of flexibility in said transmission-means, so that the feed-screw can be properly rotated even though not positioned in precise alinement with the axis of the turn-table. And,

finally, the invention consists further of the features of construction and arrangement hereinafter more particularly pointed out and claimed.

- Although the'invention may be embodied in various forms, it 'will be best understood by reference to the accompanying drawingsand the following description of a preferred embodiment applied to a'disk. talking machine; but it must be understood that the drawings and description are'not' intended to limit the invention but merely to illustrate one embodiment thereof.

In these drawings,

Figure 1 represents a plan of. a portion of a conventional disk talking-machine equipped with the new attachment;

Fig. 2 is a front elevation of the construction shown in Fig. l, but partly in vertical section and showing the clutch, members, separated; and

Fig. 3 is a transverse vertical section, also showing in elevation the worm and a portion of the worm-gear.

Referring to these nary or any suitable boxing or cabinet for a disk talking-machine, which has the usual turn-table 2 "carried by the motor-shaft whose upper end projects at 3, all as usual. Upon the center of the turn-table is laid a block 4, preferably circular, which has one or more upwardly extending studs 5 to con stitute clutch-plate for rotating the feedmechanism, as hereinafter described. These studs are preferably carried by a split-.

spring bushing '6 secured centrally in the block 4, by means of which the block may be held firmly upon the projecting end 3 of the motor shaft. Preferably the block 4 is provided with an annular groove around its circumference, in which is seated a band? of rubber or the like; and a flat recordingtablet 8, of suitable recording-material, and having a central opening adapted to snugly embrace the band 7, ma then be put in position as indicated in Figs. 1 and 2.

Uponthe cabinet 1 is screwed a bracket 9 carryin a vertical post 10 upon which is mounted t e frame carrying the feed-mechanism. As shown, th'isjframe comprises two vertical end-pieces or heads 11 and 12, held drawings, 1 is an ordiv frame rigidly in any desired adjustment across the turn-table.

. tudinally-slotted to receive the feed-screw 17 (see Fig. 3) and permit the partial feednut to engage therewith in the usual mane ner. The outer end of the screw-shaft pro-' j'ects beyond the head 12 ad carries the mesh with said worm-gear 18.

wormrgear 18.. The usual or any suitable carriage 19 for carrying a sound-box, preferably one adapted to carry interchangeably .either a recorder or a reproducer, slides upon the hollow rod 16 and one or'both of the other two rods, and .is equipped with the usual partial-nut for entering said longitudinal slot and engaging said feed-screw, and is also provided with the usual lever 20 for simultaneously lifting the recorder (or reproducer) and disengaging said nut.

In suitable bearings 21, upon the free side of the head 12, is journaled a hollow vertical shaft 22, carrying externally a worm- 23 in A volute helical spring 24 is secured at its smaller and upper end to this worm-shaft 22, and at its lower and larger end to a horizontal plate 25. A headed lifting rod 26 is splined in the bore of the worm-shaft to telescope therein, and at its lower end is provided with a disk-like foot which extends under the overhanging rim'27 secured to plate 25, but is not otherwise connected thereto. Upon the lower face 'of this plate 25 are two or more depending studs adapted to engage against the sides of the studs 5 aforesaid, so that'plate 25 constitutes an upper clutchplate adapted to co-act with the lower clutch-plate aforesaid; and, if desired, said plate 25 may have a depending central boss adapted to enter the bore in the "lower clutclimember. The spring 24 and the non-positive connection between rod 26 and plate 25 constitute a flexible or resilient connection by which the worm-shaft will be properly rotated even if not precisely concentric with the axis of the turn-table and main shaft 3.

Although, as stated, any usual or suitable carriage and recorder (or reproducer) may be employed, yet in Fig. 3' is illustrated a preferred structure for this service, in which the neck or stempf the recorder (or repro-v ducer) 28 is shown as detachably seated in the usual trunnion-socket that swings vertically upon the horizontalpivot 29 upon the carriage, and is provided with the up-. wardly-extending lifting-arm 30. The lifting-l'ever 20 is shown as the handle of a ring which journals around the usual sleeve slidable upon one of the guide-rods, and is provided with two cam-surfaces. .Two levers are journaled upon the same transverse pivot 31 in the carriage, of Whichthe substanfially-verficall lever 32 is'adapted at its upper end ta he acted upon by one of the through the longitudinal slot in hollow rod 16 and engage the feed-screw 17, so that the shifting of the handle 20 to the left (in Fig. 3)- not only depresses the rear end of said lever 33 and thereby disengages the feed-nut but also lifts said recorder '(or reproducer) clear from the recording-tablet,

thus putting the recorder or reproducer into inoperative position so that the operator can freel shift it along its frame-work; while shifting handle 20 to the right. (in Fig. 3) restores the parts to their operative position, preferably by aid of a double spring such as 34, secured at its center to thecarriage and bearing at one end against the upper end of lever 32 and at its other end against the outer end of lever 33. The invention has thus been set forth with considerable detail, but only for the sake of clearness since it is not limited to the preriselconstruction and'arrangement above set ort 1.

that parts of the structure can be inverted, or can be tran osed with other parts,'and that parts can used to the exclusion of other parts, without in any case departing from the spirit of the invention.
